TRAIN-LINE CONNECTION:

Specification of Letters Patent.

Patented Aug. 20, 1907.

To all whom it may cmwcm:

Beit known that I, FREDRXGK HAMMER, a citizen of the United States,residing at Columbus, in the county of Franklin and'State of Ohio, haveinvented certain new and useful Improvements in Tiain-Line Connections,of which the following is a specification.

My invention relates to train line connections and has for its objectthe provision of means for connecting the air or steam lines of a trainbetween adjacent cars, in suchmanner as to accommodate the movementbetween the cars, but at thes'ame time dispense with the usual rubberhose ordinarily employed for this purpose;

It has been found that many serious accidents have occurred by reason ofthe bursting or breaking of the The air brakes now in sure maintained inthe train line. If this pressure be 'suddenly and entirely released, thebrakes are instantly set with such force as to slide the wheels. Thedisastrous effects attending upon having the brakes set in this manner,upon a train running at a high rate of speed may be readily seen. It isto provide a train line connection that will be capable of movement ineither direction to accommodate the movement between the cars while thetrain is in motion and which may be made entirely of metal, therebyinsuring long life and freedom from bursting, that the present inventionis particularly designed.

In the a ompanying drawing: Figure 1 is a side elevation illustratingthis improved connection arranged between the angle cocks of the airline of two opposed cars, Fig. 2 is a plan view showing the cars indotted lines, Fig. 3 is a vertical section upon line x-x of Fig. 1, and,Fig. 4 is a detail sectional view through one of the joints of theconnection.

Like numerals designate corresponding parts in all of the figures of thedrawing.

Referring to the drawing, the numerals 5 designate two opposed cars.Angle cocks 6 of the usual and well known construction, are secured tothe pipes 7 which comprise a part of the train line. Threaded into eachof the angle cocks at 8, is a hollow stem 9. This stem is provided witha flange 10, an angular portion 1] which is adapted to be engaged by awrench or like tool, a beveled portion 12, and beveled packing 13, saidbeveled packing being adapted to engage a bevelod seat 15 of an elbow16,'said elbow terminating in an outturned threaded flange 17. A cap 18is threaded upon this flange and engages the beveled portion 12.

and the flange 10 to press the packing 13 firmly into engagement withthe seat 15. The cap 18 has a down wardly extending lug 19 whichreceives a set screw 20, the inner end of said set screw bindingagainstthe elbow 113 to prevent the cap 18 from turning with relation tosaid elbow. 'Said cap and said elbow, however,

both turn with relation to the sleeve 9. Threaded into the elbows 16 areshort downwardly inclined pipes 21,

said pipes extending from the angle cocks beneath the draw bars whichhave been illustrated in dotted lines.

in Fig. 2. The provision of these pipes 21 extending beneath the drawbars, brings the rest of the structure into longitudinal alinernentbeneath the draw bars. The ends 22 of these pipes are downturned and arethreaded into the angular portions 23 of hollowstems similar to thehollow stems 9,,the angular portions 23 corresponding to the angularportion 11 of the stem 9. The joints formed by these portions areindicated by the reference numerals 24, said joints being in everyrespect similar to the joints formed by the parts 9 to 20. Furtherdescription of these joints is therefore believed to be unnecessary. I

Threaded into couplings 25 which correspond to the coupling 16 of thepreviously described joint, are short preferably curved pipes 26,-theouter ends of which are connected by elbows 27 with the stems 28 ofjoints 29, these latterjoints being similar in all respects to thepreviously described joints, except that they lie in a vertical insteadof a horizontal plane.

Elbows 30 of these latter joints, which correspond to the elbows 25 ofthe previously described joints, are connected by short preferablycurved pipes 31 with the elbows 32 of joints 33, said joints 33 beingsimilar to the joints 29. Elbows 34 connect the joints 33 with pipes 35,V Coupling members 36 adapted to engage with each other, and eonstructedlike the usual couplings used to connect the air hose now in use, areprovided upon the outer ends of these pipes. Those coupling members formno part of the present invention and consequently require no furtherdescription.

From the foregoing description, it will be seen that the pipe 21 isadapted to swing in a horizontal plane from the first of the jointsdescribed, together with all of the parts carried thereby, The partscarried by the joints 24 are likewise adapted to swing bodily from saidjoint in a horizontal plane. The joints 29 and 33 permit verticalmovement of the parts, these double joints permitting considerablevertical movement without varying to any considerable extent the angleof the pipes 35 and consequently permitting the coupling members 36 toreadily engage with each other. It will therefore be seen that simpleand efiicient means have been herein provided for accomplishing theobjects of the invention, but while the elements shown and described arewell adapted to serve the purpose lor which they are intended, it is tobe understood that the invention is not limited to the preciseconstruction set forth, but includes within its purview such changes asmay be made within the scope of the appended claims.

What I claim, is:

1. in a device of the character described, the combination with asection of metallic pipe, of means for securing said pipe to a trainline at one end 01 a car in such manner that said pipe is adapted toswing horizontally from said connection, said pipe extending fromthe-train line, beneath the draw bar, a second section of metallic pipehaving air tight connection with the tirst named section and adapted toswing in a horizontal plane with relation thereto, a third section ofpipe having air tight connection with the second named section andadapted to move vertically with relation thereto, and means forconnecting the last named section to the coupling member of an adjacentcar.

2. in a device of the character described, the combination with asection of metallic pipe, of means for securing said pipe to the trainline of a car at one end thereoi in such manner that said pipe may beswung in a horizontal plane, a second section of pipe having air tightconnection with the first named section and adapted to swing in ahorizontal plane with relation thereto, a third section or pipe havingair tight connection with the second section and adapted to move in avertical plane with relation thereto, a fourth section of pipe havingair tight connectionwith said third section and adapted to more in a vertical plane with relation thereto, and a coupling member carried'uponsaid last named section which is adapted to engage with the couplingmember oi an adjacent car.
